Biliopancreatic Diversion D/S

Hi, I am Terri and I am new to all of this. I am very excited to know that there are people out there who have had WLS that I can communicate with. I am trying to find the Statistics on a Doctor in Louisville, that does the BPD-D/S. Does anyone out there no how I go about finding out how many Surgeries a Doctor has preformed and which type. I know he has done over 900 surgeries and is very highly recommended, but how do I go about finding out how many of them were actually the D/S?? Is there some sort of web-site that I can go to that will tell me this. He is not listed in the State of Ky. as doing the D/S, but I know that he does them. He was also very highly recommended to me by a Doctor that I work with that said he went to School with him and he is an Awsome Surgeon. He always excelled in everything that he done in Med School. I just don't know how to find out how many of this particular procedure he has done. Please, can anyone help me. Thanks, Terri
